/* Why is this a namespace and not a class?
 *
 * 1) We want it to behave like a singleton without an instance() method. This
 * would normally be accomplished by using a set of static methods and member
 * variables.
 *
 * 2) We need to extend the contents of the (class|namespace) in
 * gtk2_ardour. We can't do this with a class without inheritance, which is not
 * what we're looking for because we want a non-instance singleton.
 *
 * Hence, we use namespacing to allow us to write ActionManager::foobar() as
 * well as the extensions in gtk2_ardour/actions.h
